It’s pretty unusual and inconvenient that I do not have an option to find my messages 
We have this on our list of things to do 
An interim measure is to look into the respective forum for a thread that jogs your memory…
I have to agree in that the forums do need a lot of work. It really just need to be more efficient - the community is a big part of LingQ after all. Improvements are always welcome
The forum is very simple but very efficient.
To me just perfect.
I tend to remember certain key words in posts I want to find again, but I agree that a more intelligent search tool would be great.
I think before waiting improvements from others we should try to improve ourselves first.
